Entropic Priors and Bayesian Model Selection (2009)
Brewer, Brendon J., Francis, Matthew J.
We demonstrate that the principle of maximum relative entropy (ME), used judiciously, can ease the specification of priors in model selection problems. The resulting effect is that models that make...
Gaussian Process Modelling of Asteroseismic Data (2009)
Brewer, Brendon J., Stello, Dennis
The measured properties of stellar oscillations can provide powerful constraints on the internal structure and composition of stars. To begin this process, oscillation frequencies must be extracted...
Riechers, Dominik A., Walter, Fabian, Brewer, Brendon J., Carilli, Christopher L., Lewis, Geraint F., Bertoldi, Frank, ...
We present high-resolution (0.3") Very Large Array imaging of the molecular gas in the host galaxy of the high-redshift quasar PSS J2322+1944 (z = 4.12). These observations confirm that the molecular...
Applications of Bayesian Probability Theory in Astrophysics (2008)
Bayesian Inference is a powerful approach to data analysis that is based almost entirely on probability theory. In this approach, probabilities model {\it uncertainty} rather than randomness or...

The Implications of the Early Formation of Life on Earth (2008)
One of the most interesting unsolved questions in science today is the question of life on other planets. At the present time it is safe to say that we do not have much of an idea as to whether life...
Unlensing HST Observations of the Einstein Ring 1RXS J1131-1231: A Bayesian Analysis (2008)
Brewer, Brendon J., Lewis, Geraint F.
We present a source and lens reconstruction for the optical Einstein ring gravitational lens system RXS J1131-1231. We resolve detail in the source, which is the host galaxy of a $z=0.658$ quasar,...
Riechers, Dominik A., Walter, Fabian, Brewer, Brendon J., Carilli, Christopher L., Lewis, Geraint F., Bertoldi, Frank, ...
We present high-resolution (0.3") Very Large Array (VLA) imaging of the molecular gas in the host galaxy of the high redshift quasar PSS J2322+1944 (z=4.12). These observations confirm that the...
Getting Your Eye In: A Bayesian Analysis of Early Dismissals in Cricket (2008)
A Bayesian Survival Analysis method is motivated and developed for analysing sequences of scores made by a batsman in test or first class cricket. In particular, we expect the presence of an effect...

Solar-like oscillations in the G2 subgiant beta Hydri from dual-site observations (2007)
Bedding, Timothy R., Kjeldsen, Hans, Arentoft, Torben, Bouchy, Francois, Brandbyge, Jacob, Brewer, Brendon J., ...
We have observed oscillations in the nearby G2 subgiant star beta Hyi using high-precision velocity observations obtained over more than a week with the HARPS and UCLES spectrographs. The oscillation...
Bayesian Inference from Observations of Solar-Like Oscillations (2006)
Brewer, Brendon J., Bedding, Timothy R., Kjeldsen, Hans, Stello, Dennis
Stellar oscillations can provide a wealth of information about a star, which can be extracted from observed time series of the star's brightness or radial velocity. In this paper we address the...

Asteroseismology is a powerful method for determining fundamental properties of stars. We report the first application to a metal-poor object, namely the subgiant star nu Ind. We measured precise...

The Einstein Ring 0047-2808 Revisited: A Bayesian Inversion (2006)
Brewer, Brendon J., Lewis, Geraint F.
In a previous paper, we outlined a new Bayesian method for inferring the properties of extended gravitational lenses, given data in the form of resolved images. This method holds the most promise for...

Strong Gravitational Lens Inversion: A Bayesian Approach (2005)
Brewer, Brendon J., Lewis, Geraint F.
If an extended source, such as a galaxy, is gravitationally lensed by a massive object in the foreground, the lensing distorts the observed image. It is straightforward to simulate what the observed...
When Darwin Met Einstein: Gravitational Lens Inversion with Genetic Algorithms (2005)
Brewer, Brendon J., Lewis, Geraint F.
Gravitational lensing can magnify a distant source, revealing structural detail which is normally unresolvable. Recovering this detail through an inversion of the influence of gravitational lensing,...
Probing Sub-parsec Structure in the Lyman Alpha Forest with Gravitational Microlensing (2004)
Brewer, Brendon J., Lewis, Geraint F.
We present the results of microlens ray-tracing simulations showing the effect of absorbing material between a source quasar and a lensing galaxy in a gravitational lens system. We find that, in...
